4 hours of Martin Scorsese chronicling the life and musical career of in my opinion, the most interesting Beatle.
He wrote some really great songs, talked Clapton into the guitar solo on While My Guitar Gently Weeps, and hung out with the Monty Python gang. He actually mortgaged his house in order to bank roll the production of Life of Brian, to the tune of $4,000,000.

It's a really good watch, and not trying to pimp Amazon, but it's on Prime Video.

I can't believe I had never seen this until today, I must be living under a rock sometimes.
